How to create a boot/root maintenance disk for Linux This document describes how to design and build your own boot/root diskettes for Linux. These disks could be used as rescue disks or to test new system components. If you haven't read the Linux FAQ and related documents, such as the Linux Installation HOWTO and the Linux Install Guide, you should not be trying to build boot diskettes. If you just want a rescue disk to have for emergencies, see Appendix Pre-made bootdisks.
